I think it was $18 for a 90 day supply. They also have big bottles of Vit. D!

I couldn't get along without Costco. It used to pay for itself just in terms of dog food. Now that we no longer have a dog...We have the Costco American Express card and we get about a $500 rebate every year. We also get a rebate from Costco that covers the membership fee every year. Dh and I also get out movie tix there---2 Regal or AMC tix for $15. That's a deal these days!
